LOG-CAR DOG.

Specification of Letters Patent.`

Patented May 28, 1907.

Application filed September 24,1906. Serial No. 385,951.

To all whom it may concern,.-

Be it known that I, JOHN HANLEY, a citi- Zen of .the United States,residing at Laurel, in the county of Jones and State of Mississippi,have invented a new and useful Log- Car Dog, of which the following is aspecification.

This invention relates to log cars and simi-- lar vehicles and relatesmore particularly to an improved dog or standard designed to be attachedto the cross beams or bolsters of the car, whereby the logs can beretained in position while in transit and can be conveniently unloadedwithout the danger to the workmen incident to the unfastening of thechains hitherto commonly employed for retaining the logs in place.

The invention has for one of its objects to improve and 'simplify theconstruction and operation of devices of this character, so that theycan be manufactured at comparatively little cost, readily installed,conveniently operated, and are efcient'and reliable in use.

A further object of the invention is to provide a pivotally mountedstandard on a suitable supporting frame attached to the car bolster, orother convenient part, and a locking mechanism which is operated'fromthe end of the bolster opposite from the dog for firmly holding the dogin an upright position,

j or for releasing the dog.

With these objects in view, and others, as will appear as'the nature ofthe invention is better understood, the invention comprises the variousnovelfeatures of construction and arrangement of parts, which will bemore fully described hereinafter and set forth with particularity in theclaims appended hereto. V In the accompanying drawing, which illustratesone of the embodiments of the invention, Figure 1 is an end view of alog car with the dog attachment applied' thereto. Fig. 2 is afragmentary end view of the car showing the dog released and in theposition occupied during the unloading of the car. Fig. 3 is an enlargeddetail view of the dog or standard and the supporting frame therefor.Fig. 4 is an end view of one of the dogs and its supporting frame. Fig.5 is a perspective view of a modified form of supporting frame.

Corresponding parts 1n the several gures are indicated throughout bysimilar characters of reference.

Referring to the drawing, 1 designates one of the cross beams orbolsters of the log car which at one end is provided with a shortstationary standard 2 and at the opposite end with a pivoted standard ordog. 3. The dog 3 is pivotally mounted on the frame 4 suitably securedon one of the vertical sides of 6o the bolster. The frame 4, which ispreferably of iron, comprises two spaced parallel plates 5- and 6 Theplate 5 is somewhat longer than the plate 6 and the two may beintegrally connected or formed of one piece, as shown in Fig. 5, or theymay be made of separate pieces secured together by bolts 7, as shown inthe other figures.. The dog 3 is disposed between the plates 5 and 6adjacent their outer ends and fulcrumed approxi- 7o mately at a medialpoint, on the bolt or pivot 8 arranged adjacent the upper, outer cornerof the supporting frame.

v Between the two plates is provided a stop or abutment 9 on which thedog engages in 75 both its upright and horizontal positions. This stopor abutment is formed either by a lug extending at right angles from oneof the plates, as shown in Fig. 4, or by the connecting web 10 betweenthe outer ends of the 8o plates, as shown in Fig. 5. The inner end ofthe dog 3 disposed between the plates 5 and 6 is adapted to abut theinner vertical surface 11, when the dog is locked in an upright positionshown in Figs. 1 and 3, and is adapt- 8 5 ed to abut the topy surface 12of the lug or abutment 9 when the dog is in its open position, as shownin Fig. 2.

The mechanism for locking and releasing the standard comprises a lockingmember 13 in the nature of a bell crank lever which is pivoted at itselbow on the bolt 14 disposed inwardlyv in a lateral direction from thelower end of the dog 3. The locking member 13 is arranged between theplates of the supporting frame 4, and the extremity of the arm 15 isadapted to engage the lower end of the dog on the side opposite from theabutment 9. The other arm of the locking member extends downwardly andis connected at its free end with a link 16. The link 16 extends alongone side of the bolster and may i be attached directly to an operatinglever 17 fulcrumed on the bolster 1 adjacent the end opposite from thedog 3. By preference, however, the link 16 is connected with a secondarylever 18 fulcrumed on the bolster at a point below the inner end of thesupporting frame 4. The free end of the intermediate lever is connectedwith the operating lever 17 by the connecting rod 19, the arrangement othe mechanism between the locking mem- IIO ber 13 and operating leverbeing such as to constitute a power multiplying means.

Any suitable device may be employed for limiting the throw of theoperating lever 17, a`simple form of such device being spaced pinsarranged in the bolster so as to form 4 stops adapted to engage thelever adjacent its lower or handle end. The supporting frame of theconstruction shown in Fig. 5 is provided with a depending arm 21 towhich the intermediate lever is pivotally bolted. The advantage of thisform of frame is that the operating parts of the device can be assembledthereon in the shop and all that is necessary for applying it to a caris to bolt the frame to the bolster and then the lever 17.

kIn operating the device, the operating lever 17 is shifted to the rightso as to throw the locking member 13 to the'position shown in Fig. 1 forengaging with the dog 3, the latter having been raised to its verticalposition before the throwing of the operating lever. The locking member13 is arranged to have its upper arm 15 with its longitudinal dimensiondisposed at right angles to the dog or in tangential relation to its areof movement, so that any outward pressure on the upper end of the dogoperates directly in line with the arm 15 and the fulcrum 14. The lowerend of the dog is thus iirmly held between the end of the arm 15 and theabutment 9 of the supporting frame, so that the dog is positively lockedin an upright position. Assuming that the car is to be unloaded, allthat is necessary is to pull the operating lever 17 to the left, therebyreleasing the lower end of the dog by the locking member 13 moving tothe position shown in Fig. 2. The lateral pressure of the logs on thecar will swing the dog outwardly, so that the logs can drop oit over thedog and roll down the skids.

It will be noted that the locking member and dog are not mechanicallyconnected, so that the dog is turned to its upright position by handwhile the locking member is in the position shown in Fig. 2, in whichposition the arm 15 is out of the path oi movement of the lower end ofthe dog. After the dog is moved to its upright position, the lever 2O isshifted to the right so .as to cause the-member 13 to lock the standardin place.

While only one dog and actuating mechanism has been described, it is tobe understood that at least two dogs will be employed, one at each endofthe ear, and, if desired, a larger number may be used.

I have described the principle of operation of the invention, togetherwith the apparatus which I now consider to be the best embodimentthereof, but I desire to have it understood that the apparatus shown ismerely illustrative, and that various changes may be made, when foundexpedient, as are within the scope of the invention.
